Mushroom Body Microcircuit

The mushroom body (MB) is the fly’s learning and memory center — a microcircuit of ~6,300 neurons that transforms dense olfactory input into sparse, associative representations. It is the first circuit explored end-to-end in BRAVLi, and the subject of a research manuscript. Lessons Covered Lesson 05 — Explore the Mushroom Body Integration: complete factsheet and visualisation of the MB. Kenyon cells (KC), projection neurons (PN), dopaminergic neurons (DAN), and mushroom body output neurons (MBON) — populations, connectivity, and spatial arrangement. ...
